Description
The Cleveland Controls AFS-262-121 Air Pressure Sensing Switch is used to measure air pressure in a range of 0.05-2.0” WC. It uses an SPDT switch which turns on or off an electrical circuit depending on pressure. This switch is designed to be used in systems, like air handlers or ductwork that are used in HVAC to ensure that air passes as it needs to, while preventing damage to equipment that is used. Advantages of this switch include increased system performance due to proper airflow regulation, safety risks that are identified by pressure variations, and accurate control of the ventilation and other HVAC procedures.
